I'm running into an issue with my product search. When a customer does a search, then clicks on an item, I wind up getting a 522 error. I'm currently using varnish, magento cache, and a CDN.
If I try to open the item from the category page, it opens just fine. But if I try to open it from a search results page, then it errors out.
I get this error using either Like or Fulltext.
